  • Patent number: 10596794
    Abstract: A carrier film of thermoplastic polyester has releasable metal adhesive properties suitable for a metal transfer in which the polyester film is metalized and the metal layer is subsequently transferred to a permanent adhesive-coated substrate. The metal layer is in direct contact with the polyester carrier film and no intermediate release layer is present. Desired metal adhesion is provided by dispersing an suitable surfactant, and optionally, a hydrocarbon wax, uniformly into the polyester film. Surfactant on the outer surface of the carrier film modifies metal adhesion to the polyester such that the metal can be removed in a metal transfer operation.
